Abstract
Description
technical field
[0001] The invention relates to the field of automatic control in industrial processes, in particular to an industrial mass production control method. Background technique
[0002] The industrial production process is divided into continuous production process, batch production process and discrete production process according to whether the output products are continuous product flow, discrete batch product flow or discrete quantity of products.
[0003] Among them, the batch production process is composed of more than one operation performed in a certain order, and the completion of these operations can produce a certain number of final products. If more quantities need to be produced, these steps need to be repeated.
[0004] In the mass production process, the number and types of field devices are many. Taking the bulk method PVC (polyvinyl chloride) production process as an example, most of the equipment used are two-position control equipment, such as...
